I have an asus m4a89gtd pro/usb and a phenomII x2 555BE.
I have tried the core unlocker, but it hasn't worked. I understand that the locked cores may be faulty and un usable, but heres the strange thing. When I disable the cores one at a time and two at a time, Windows (7 64bit) won't even try to load. I have tried all the cores (except #1)and the same happens. Surely if two cores are faulty it should still boot up on the two good cores? It seems as if it just wont boot when using core unlocker feature rather than a definate core problem.
